 GPI [INPUT]/[OUTPUT] connectors For connecting GPI-equipped devices. The connector type is D-Sub 25-pin female. Use the MMP1 Editor for detailed GPI settings of the unit. Refer to "Specifications" for current and voltage of each pin, and for pin assignments.  Dante [LINK/ACT]/[1G] indicators Display the communication status of the Dante [PRIMARY] and the [SECONDARY] connectors. LINK/ACT These indicators flash rapidly if the Ethernet cables are connected properly. 1G These indicators are lit when the Dante network is functioning as Giga-bit Ethernet.  Dante [PRIMARY]/[SECONDARY] connectors For connecting to the Dante network. The connector type is etherCON (RJ-45). A connector can transfer up to 64 channels (in/out) of audio. NOTE • Use an STP (Shielded Twisted Pair) cable of CAT5e standard or better to prevent electromagnetic interference. Make sure that the metal parts of the plugs are electrically connected to the STP cable shield by conductive tape or comparable means. • For connecting only Dante-compatible devices or GbE- compatible devices (including a computer). ? WORD CLOCK [IN]/[OUT] connectors For connecting devices to receive or transmit word clock signals. The connector type is BNC. The WORD CLOCK [IN] connector is internally terminated by a 75 ohm resistor.  ANALOG [INPUT 1-8]/[OUTPUT 1-8] connectors For connecting devices to transmit or receive analog audio signals. The connector type is 25-pin D-Sub (balanced). A connector can transfer up to eight channels (in/out) of audio.  [AES/EBU 1-8]/[AES/EBU 9-16] connectors For connecting devices to transmit or receive AES/EBU format digital audio signals. The connector type is 25-pin D-Sub. A connector can transfer up to eight channels (in/ out) of audio. NOTE Use a shielded cable to prevent electromagnetic interference. Make sure that the metal parts of the plugs are electrically connected to the cable shield by conductive tape or comparable means. 2. Names and Functions MMP1 Getting Started 11
